Advanced Energy Materials, EarlyView.Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...

Child Abuse Review, Volume 32, Issue 1, January/February 2023., 2023 Abstract Whatever the circumstances, the separation of infants from their mothers at birth is a traumatic experience for all concerned. The paper reports on a study designed to improve practice in this highly sensitive area. An analysis of data collected through semi‐structured interviews with 38 mothers who had experienced removal at birth identified ...

Rapid Access to Conjugated Z,Z,Z‐Trienes
Angewandte Chemie, EarlyView.Z,Z,Z‐triene: A novel method to facilitate rapid access to the otherwise inaccessible conjugated Z,Z,Z‐triene motif is reported. Abstract Intercepting reactions have recently emerged as an innovative approach in organic synthesis, allowing chemists to harness reactive intermediates to access structures and functionalities that conventional methods ...

Spontaneous changes a basis for new ornamental woody plant cultivars [PDF]
Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2006 In nursery stock production of some ornamental woody plants the appearance of spontaneous variability was identified in the form of atypical pigmentation of leaves (albinism, variegated, red colored), leaves shape (jaggy) and dwarfs.

Advanced Energy Materials, EarlyView.Reservoir‐free cells do not use lithium metal during cell preparation. Instead, lithium is electrodeposited during the initial charging step, potentially simplifying the manufacturing of solid‐state batteries. The electrochemical properties of the electrodeposited lithium layer are governed by its morphology and microstructure. However, little is known

An Informed and Systematic Method to Identify Variable Mid-L Dwarfs
The Astrophysical JournalMost brown dwarfs show some level of photometric or spectral variability. However, finding the most variable dwarfs more suited for a thorough variability monitoring campaign remained a challenge until a few years ago with the design of spectral indices ...

Purple dwarfs: New L subdwarfs from UKIDSS and SDSS
EPJ Web of Conferences, 2013 The first L subdwarf was a discovered only ten years ago. Less than ten L subdwarfs been published in the literature to date. Metal-poor ultracool atmospheres has not been well understood.

A Possible Brown Dwarf Companion to the White Dwarf GD1400 [PDF]
, 2004 An unresolved, likely L dwarf companion to the DA white dwarf GD1400 is reported. This would be only the second such system known, discovered 17 years after the prototype L dwarf, GD165B, was determined to be a companion to a white dwarf. Photometric observations and model predicted stellar parameters of the well studied white dwarf primary indicate ...
